Hello, i learned how to make maps, but the compiler can't compile the map. I read some online posts, it seems the problems comes from "brushes" and "leaks", things i don't know what they are. However, i'm 100% sure my map doesn't contain errors, because i'm doing it correctly.
Here is a video about how exactly i build the map:

Watch the video and tell me if i do it wrong. Basically, i make a hollow box, then add textures (walls, road, sky) and a light source. That's it. I made a simplistic map for the sake of the video, just to show you the error.
Sorry for the black bars and the low quality of the video.
So, what do you think? Is the error caused by me doing something not in the right way, or what? Also, if Valve Hammer Editor can't compile the map, what other programs (compilers) can i use to compile the map?
The Valve Hammer Editor i use is 100% legit, i have a Steam profile and downloaded Half-Life SDK.
